white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
VisIt is an interactive parallel visualization and graphical analysis tool for viewing scientific data. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. It was designed to interactively handle very large data set sizes in the terascale range, and works well down to small data sets in the kilobyte range.
Drqueue is a distributed rendering queue. It helps manage jobs on a render farm. It works under Linux, Mac OS X, FreeBSD, IRIX, and Windows, supports Maya, Blender, Lightwave, Mental Ray, Bmrt (Renderman), 3Delight, and Pixie out of the box, and can support any other renderer or computing task that can be handled via scripting.
OpenEXR is a high dynamic range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. It includes support for 16-bit floating-point pixels (compatible with NVIDIA's Cg shader language "half" datatype), several lossless compression algorithms, and extensible image metadata attributes.
EQUINOX-3D is a 3D modeler with a very fast, fully integrated ray-tracer. It features read/write support for COLLADA, read support for Radiance's .hdr image format, 3DS (3D-studio) file format read support, multi-texturing, custom-programmable texture mapping, bump-mapping with automatic texture-space tangents, the ability to zoom into a region with "fly-to", and more. It includes a full runtime-class framework and a core design that allows for the addition of anything from a physics engine to a fully integrated renderer from a plugin. It is faster and more memory efficient than many other modelers.
PLIB is a set of libraries to write games and other realtime interactive applications that are 100% portable across a wide range of hardware and operating systems. It's used by Majik3D, FlightGear, and others, and includes libraries for GUI widgets, sound replay, geometry, scene graph, joystick, and fonts/text.
QGLViewer allows people programming in OpenGL to play around with three dimensional scenes or to write software that uses OpenGL. It provides a set of classes for camera control, as well as comfortable user interface that allows you to control your viewing parameters via mouse and buttons. A framework for camera paths and their interpolation is provided, as is a simple scene tree. QGLViewer is object oriented and programmed in C++ such that the programmer simply instantiates a viewer and connects it to their own render routines.
